Description

Technical Field

[0001] The utility model belongs to the technical field of electronic cigarettes, and particularly relates to a forming structure of a hardware elastic sheet, a cartridge accessory and an electronic cigarette. Background Art

[0002] An electronic cigarette is an electronic product that imitates a cigarette. Through an atomization device arranged inside, the e-liquid is atomized into an aerosol by heating or high-frequency oscillation, etc., for users to inhale. It can obtain a feeling highly similar to inhaling a traditional cigarette while reducing the intake of harmful substances such as tar. Therefore, it is often used as a substitute for cigarettes.

[0003] An electronic cigarette includes a cartridge and a battery device electrically connected to the cartridge. The cartridge is provided with a liquid storage cavity, a liquid absorbing member, a mouthpiece cap, etc. The liquid absorbing member adsorbs the e-liquid in the liquid storage cavity. The heating element of the electronic cigarette heats the e-liquid adsorbed on the liquid absorbing member under the electric drive of the battery device to form a smoke for users to inhale. On the cartridge, electrode contacts that are electrically connected to the heating element and the battery need to be provided, so that the battery can electrically drive the heating element to form an aerosol from the e-liquid. If there is an error in the relative position between the electrodes during the forming process of the electrode or the accessory containing the electrode, problems such as poor contact or inability to connect may occur. Therefore, relatively high requirements are placed on the relative position of the electrode contact setting. Summary of the Utility Model
